Investigation of the Intrinsic Defects of LiTaO 3 Crystals by NMR Spectroscopy

Investigation of the Intrinsic Defects of LiTaO 3 Crystals by NMR Spectroscopy Abstract The nuclear magnetic resonance (NMR) of 7Li and 6Li nuclei in a LiTaO3 single crystal sample of congruent composition has been experimentally investigated. It is found that there are weak side lines in the NMR spectra of 7Li nuclei, which have not been observed before; these lines are due to cation sublattice defects. A computer simulation of NMR spectra has revealed the most likely configuration of \(({\text{Ta}}_{{{\text{Li}}}}^{{{\text{5}} + }} + {\text{4}}{{V}_{{{\text{Li}}}}})\) defect complexes that are present in nonstoichiometric LiTaO3 crystals. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Crystallography Reports Springer Journals

Abstract

Abstract The nuclear magnetic resonance (NMR) of 7Li and 6Li nuclei in a LiTaO3 single crystal sample of congruent composition has been experimentally investigated. It is found that there are weak side lines in the NMR spectra of 7Li nuclei, which have not been observed before; these lines are due to cation sublattice defects. A computer simulation of NMR spectra has revealed the most likely configuration of \(({\text{Ta}}_{{{\text{Li}}}}^{{{\text{5}} + }} + {\text{4}}{{V}_{{{\text{Li}}}}})\) defect complexes that are present in nonstoichiometric LiTaO3 crystals.
